Abstract

1335570 Injection nozzle/mould relationship K AOKI 9 Dec 1970 [9 Dec 1969 25 March 1970] 19331/73 Divided out of 1335567 Heading B5A The invention relates to apparatus of the same type, Figs. 1-5 (not shown) as described in Figs. 1-5 of the parent Specification 1,335,567. According to the invention, Figs. 6 and 7, the injection nozzle 15 extends downwardly from the upper part 11a of the clamping structure 11 in which it is housed, and the clamping stroke of an upwardly acting clamping ram 13 is reduced by providing, from one edge of each of plates 5, 51 supporting the upper mould parts 4b, 4b<SP>1</SP>, a slot 56, 561 into which the nozzle 15 projects during movement of each mould 4, 4<SP>1</SP> on the plate 2 into and out of the clamping device 11.
